just a moment ago I was looking at Tyson's tail and I found something strange and I'm soooo afraid that it's something very wrong!..I found like a ring before the tip of his tail that skin got off and it looks like if it's falling off..the ring is a greyish colour and it's like a hole all around his tail on that spot(which is right before the tip of his tail) what might it be!?looks like the tip's going to fall off and he doesn't like it when we touch it and sometimes he tries to bite it..I can tell it's bothering him,does anyone know what it might be!?
